ProblemMany language learners struggle with speaking because feedback often feels evaluative rather than supportive. This can increase pressure and reduce willingness to continue practicing.

GoalDesign a feedback-driven interaction system that helps users practice speaking with more confidence and less friction.

My roleI developed the product concept, designed the interaction flow, structured the feedback experience, and shaped the UI system across core screens including speaking practice, vocabulary interaction, progress tracking, and account management.

Supportive feedback over corrective toneFeedback was designed to guide users without increasing pressure, helping transform evaluation into encouragement.

Interaction as a continuous loopThe core experience connects prompt, speech, feedback, and repetition into a loop that supports gradual improvement.

Progress visibility as motivationA progress layer was introduced to help users see development across fluency, pronunciation, grammar, vocabulary, and coherence.

The progress system was designed to help users understand their development over time, not just their performance in a single session.Instead of presenting isolated scores, the system visualizes changes across fluency, pronunciation, grammar, vocabulary, and coherence, allowing users to see patterns and gradual improvement.By comparing current and previous performance, the feedback becomes more meaningful and encourages continued engagement.
